A few additional higher-resolution photos of the TM2 source tray with new spacer ITA6270, and bent copper ground line clip.

Also attached is a photo of a 3/8" copper line placed in between the loose ECR line and the Mounting Support Plate line, for dimensional reference.

Ultem high voltage spacer installed and 9 pin banana plug plugged in. Target has been inserted into the hot cell and will be installed after base-line electrical checks...probably first thing in the morning.

Gas lines extensions installed yesterday were too long and gas lines touched top inside of containment box. They have been removed and the gas lines re-installed in their original manner. Gas lines have been "adjusted" as to clear the tube heater lines, which was the original issue.

  1000   Thursday, July 16, 2015, 14:36 chad fisherSouth Hot-CellRepairTM2 TM2 Status

IMG gauge, clip for ground to window lines and gas line extensions were installed today.

David and I also tried to locate the short between the coil line and MSP/Heat Shield...it went away for a bit...but is back.

  998   Wednesday, July 15, 2015, 11:18 David WangSouth Hot-CellRepairTM2 leak check coil line(R,U) on TM2 at SHC

Chad and I leak checked the coil 1 circuit(R,U) after rebuilt coil line is installed on TM2 source tray. The pumping down on the circuit is very quick and smooth. The LD base lake rate 0.0xE-9 atm.cc/sec. Base pressure0.0xE-4 torr.

Chad sprayed lots helium on the R( coil 1+)and U(coil 1 -) water blocks. During  1 minute waiting time, there is no any response on LD. The R and U water blocks and C-seals are leak tight.

  997   Wednesday, July 15, 2015, 11:02 chad fisherSouth Hot-CellRepairTM2 TM2 Coil Line Vacuum Leak Check

TM2 coil line R,U has been vacuum leaked check at the hot cell and has passed with no response from the leak detector.

  996   Wednesday, July 15, 2015, 09:44 chad fisherSouth Hot-CellRepairTM2 Coil Line replacement

water block jig installed, module side sealing surfaces re-polished and cleaned. Coil line inserted into the hot cell and installed onto the module. Bolts torqued to 90 in.lbs. Received .13mSv.

  995   Tuesday, July 14, 2015, 12:56 chad fisherSouth Hot-CellRepairTM2 TM2 containment box removed

Containment box was removed from Tm2 this morning  in preparation for installation of coil line and all the trimmings.

  994   Tuesday, July 14, 2015, 08:42 Travis CaveSouth Hot-CellStandard OperationTM2no targetModule moved

TM#2, no target, has been moved from the north east silo to the south hot cell.

TM#1 has been moved back to the south west silo from the conditioning station.

  992   Friday, July 10, 2015, 14:41 Anders MjosConditioning StationMaintenanceTM1 Replaced roughing pump

 The roughing pump was replaced with a more leak tight pump due to the discovery of Rn-220 migration while roughing on TM1 in TCS

  991   Friday, July 10, 2015, 09:33 chad fisherSouth Hot-CellRepairTM2 Coil Line Decon

Coil line has been in RPG's ultrasonic decon over night. Initial swipes this morning picked up 5000 counts. It has been decontaminated to the point no more contamination is being found and nothing can be found with the frisker...so...it's ready for Maico and Dan?

  990   Thursday, July 09, 2015, 14:02 David WangConditioning StationDevelopmentTM1 TM1 is pumping down at CS

TM1 and CS  vacuum system are connected. All turbo-pumps are started. The new TP1S works fine also. The pumping down looks good so far. During the TM1 and CS roughing down time, Joe .M noticed a Rn-220 level surge up in TH . Then,the Rn220  level slowly dropped back. Anders suspected this Rn-220 surging is related to the TM1 roughing down at CS. We decided we will stop the pumps , vent the CS , and roughing  again tomorrow. During the same time Joe will monitor  Rn-220 level in TH to see if the surging is repeatable. We want to learn more on this TH Rn-220 issue.

  989   Thursday, July 09, 2015, 13:51 chad fisherSouth Hot-CellRepairTM2 Coil line removal hot cell

coil line has been removed from the hot cell. Initial decon was performed...after it still appears to have approximately 200 counts. It will now be transfered to the rad waste decon facility for further decon.

TM#2 has been moved from the south hot to the north east silo. TM#1 has been moved from the south west silo to the conditioning station.

  986   Wednesday, July 08, 2015, 14:48 chad fisherSouth Hot-CellRepairTM2 TM2 Status

Water block jig has been removed. Stuck source tray side water block jig component has been removed. An attempt was made to connect the gas lines to there bracket however they contact/interfer with the tube heater lines...Anders is looking into a solution.

Containment box and front cover have been replaced and TM2 is ready to move to the silo.

  985   Wednesday, July 08, 2015, 14:24 David WangSouth Hot-CellRepairTM2 TM2 pressure bubble test on RU water blocks.

July-06, 2015. Chad , Grant and I did the bubble test on R,U water blocks. We suspected the leak on the R,U circuit is from C seals on the water blocks so we did this test first. I applied both air and helium to R,U circuit , Chad applied snoop soap on the R,U water blocks.The air and helium pressure was increased from 40 psi to 90 psi Max step by step.Chad did not see any bubbles on the water blocks during the test. Since we did not find the leak source, we decided to do vacuum helium check on the all joints and c-seals of the R,U lines later.  Finally, We found the leak by vacuum helium spray the day after this bubble test.
